Antiguraleus adcocki is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae. [1]

Sea snail common name for snails that normally live in saltwater

Sea snail is a common name for slow moving marine gastropod molluscs usually with visible external shells, such as whelk or abalone. They share the taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible shell.

Family is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as being the "walnut family".

Mangeliidae is a monophyletic family of small to medium-sized, predatory sea snails, marine gastropod mollusks in the superfamily Conoidea.

Description

The length of the shell attains 14 mm.

(Original description).This is an elegantly formed shell, with a very acute spire and moderately attenuated base. The ribs are numerous, thick and rounded, crossed by numerous rather faint spiral sulci.

Spire (mollusc)

A spire is a part of the coiled shell of molluscs. The spire consists of all of the whorls except for the body whorl. Each spire whorl represents a rotation of 360°. A spire is part of the shell of a snail, a gastropod mollusc, a gastropod shell, and also the whorls of the shell in ammonites, which are fossil shelled cephalopods.

G.B. Sowerby III proposed in 1896 the name Mangilia adcocki as a nomen novum for the Mangilia bella of Adams and Angas (Proc. Zool. Soc. 1863, p. 419, pi. xxxvi, fig. 6), their name being preoccupied by Hinds. G.W. Tryon (Manual of Conchology, vol. vi, p. 270) considered it identical with Mangelia boakei , Nevill, a Ceylon shell with which from the figure and description, it seems to me to have but little affinity. Adcock's list gives as a synonym Mangilia gracilima, Tenison -Woods, but I have sought the records in vain for the name. [2]

In biological nomenclature, a nomen novum, new replacement name is a technical term. It indicates a scientific name that is created specifically to replace another scientific name, but only when this other name cannot be used for technical, nomenclatural reasons ; it does not apply when a name is changed for taxonomic reasons. It is frequently abbreviated, e.g.nomen nov., nom. nov..

Charles Hedley stated in 1922 :"Sowerby changed the name of this species on the ground that Mangilia bella was preoccupied by Hinds, but as a matter of fact Mangilia was used for this species neither by Hinds nor by Adams and Angas, so that the innovation was not necessary. Tryon erred in ascribing this species to Ceylon." [3] Hedley applied the name Guraleus bellus(Adams and Angas, 1863)

Charles Hedley Australian zoologist

Charles Hedley was a naturalist, specifically a malacologist. Born in Britain, he spent most of his life in Australia. He was the winner of the 1925 Clarke Medal.

The Atlas of Living Australia considers Guraleus bellus a synonym of Marita bella (Adams & Angas, 1864) [4]

Distribution

This marine species is endemic to Australia and occurs off New South Wales, South Australia, Tasmania and Victoria.

New South Wales State of Australia

New South Wales is a state on the east coast of Australia. It borders Queensland to the north, Victoria to the south, and South Australia to the west. Its coast borders the Tasman Sea to the east. The Australian Capital Territory is an enclave within the state. New South Wales' state capital is Sydney, which is also Australia's most populous city. In March 2019, the population of New South Wales was over 8 million, making it Australia's most populous state. Just under two-thirds of the state's population, 5.1 million, live in the Greater Sydney area. Inhabitants of New South Wales are referred to as New South Welshmen.

South Australia State of Australia

South Australia is a state in the southern central part of Australia. It covers some of the most arid parts of the country. With a total land area of 983,482 square kilometres (379,725 sq mi), it is the fourth-largest of Australia's states and territories by area, and fifth largest by population. It has a total of 1.7 million people, and its population is the second most highly centralised in Australia, after Western Australia, with more than 77 percent of South Australians living in the capital, Adelaide, or its environs. Other population centres in the state are relatively small; Mount Gambier, the second largest centre, has a population of 28,684.

Tasmania island state of Australia

Tasmania is an island state of Australia. It is located 240 km (150 mi) to the south of the Australian mainland, separated by Bass Strait. The state encompasses the main island of Tasmania, the 26th-largest island in the world, and the surrounding 334 islands. The state has a population of around 533,308 as of March 2019. Just over forty percent of the population resides in the Greater Hobart precinct, which forms the metropolitan area of the state capital and largest city, Hobart.
